Tony Blair's Hong Kong born sister-in-law will fly into the territory on the Prime Minister's jet to witness the handover. Katy Blair Tse Kam-har, wife of the Prime Minister's brother, is a UK expert in banking law. She and husband Bill have been invited to join the Prime Minister's party on the RAF jet which arrives here on Monday. However, it is not clear whether they will be at the actual handover ceremony. Yesterday Ms Blair said she had deep feelings for the place she grew up in and maintains a strong bond with family and friends, visiting the territory every year. 'Obviously it will be in everybody's interest that Hong Kong remains prosperous,' she said from the Chinese community centre she co-founded in London 11 years ago. Although they were travelling with the Prime Minister, they would be paying for the trip themselves, she added. Despite her keenness to avoid the limelight, Ms Blair was mentioned by the Prime Minister at the Summit of the Eight in Denver last weekend. He said the presence of a Hong Kong-born sister-in-law in his family made him very aware of the concerns of the territory. She was sent to Britain by her parents for further study and it was while working as an administrator in a London legal firm that Ms Blair met her husband. They married in Hong Kong in 1982, with Mr Blair best man. The couple live near Tony and Cherie Blair's home in Islington, north London. Ms Blair was educated at Sacred Heart Canossian College in Pokfulam and started her career as a junior clerk at Hongkong Bank.
